Specification of Letters Patent.

Patented Oct. '17, 1916.

Application led August 11, 1915. Serial No. 44,866.

To all whom t may concern Be it known that I, GRIDLEY ADAMS, a citizenof the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented new and useful Improvements inEnvelops, of which the following is a specification, reference being hadto the accompanying drawings, forming a part thereof. y

The purpose of this invention is to prof vide an improved form ofenvelop, particularly designed and adapted to be returned to theoriginal sender.

It consists in the elements and features of construction shown anddescribed, as indicated in the claims.

In the drawings: Figure 1 is a plan view of the blank from which theenvelop in question is formed. Fig. 2 is a perspective view of theenvelop' as completed ready for use and .before sealing. Fig. 3 is anelevation of the address side lof the envelop when closed and sealed.Fig. 4 is a section at the line, 4 4, on Fig. 3.' Fig. 5 is an elevationof the envelop after having been sealed and opened.

The envelop which constitutes this invention is designed to have closedends and one longitudinal edge open and adapted to be f sealed, and whenconstructed so as to serve all the purposes for which it is designed,has a flap extending from each of the sides, (front and back) at theedge which is open and adapted to be sealed. In carrying out thesepurposes the blank, A, comprises the body area, formin the two sides, 1and 2, ofthe envelop, an projecting from the end portion of one of saidparts, as for example, the part, 1, two narrow flaps, 3 and4,4perforated at the lines'forming the ends of the body or folding lineof the flap, and gummed upon the back or outer surface for, adhering tothe innersurfa'ce of the opposite side, 2,

of the 'body for closing the envelop at the ends. From the two oppositelongitudinal edges of the front and back, 1 and 2, portions, 5 and 6,extend which yare to form flaps extending from the open edge of theenvelop when 1t has been folded to close the ends; One of these flaps,5, has printed upon its inner surface the address to which the envelopis to be returned, and upon the opposite surface it may have any form ofcommunication, as, for example, instructions as to the manner of use ofthe envelop or any other communication to be responded to or acted uponby then person to whom the en# .velop is sent out and by whom it is tobe returned to the person whose address is printed upon said innersurface of said Hap, 5. The said flap, 5, is gummed around its margin onthe outer surface so that it may be folded down upon the outer surfaceof the body of the envelop and gummed thereto concealing thecommunication printed uponthe outer surface of the flap and expose theaddress printed upon the inner (which then becomes the outer) surface ofthat flap, 5. The paper is preferably perforated along the line offolding, 6a, of the flap, 6, at the open edge of the envelop. Said flap,6, is designed to ybe tucked into the envelop and the envelop is to beclosed and sealed by the adhesion of the outer surface of the flap tothe inner surface of the opposite side .of the envelop body, and forthat purpose either the flap, 6, is gummed upon rits outer surface alongthe fold and perforated line, as indicated at 10; or the inner surfaceof the opposite side, l, is gummed as shownv at 10, and both oftheseareas may be gummed without objection and with the advantage of adaptingthe envelop to be sealed with both Haps, 5 and 6, turned in or with onlythe flap, 6, turned in, or with the flap, 6,y detached and the Hap, 5,turned out,

or with both aps detached.l This ap, 6, may be wide enough to` contain aconsiderable communication which may be lin rei sponse toor incompliance with the suggestions of the communication which may beprinted upon the outer side of the flap, 5, and concealed when the flapis folded down to expose the address as above described.

' Such communication is indicated at l1 on the outer surface of theflap, 6, by the opening address and lines ruled for writing, and on theopposite surface of 'the flap by the ruled lines and conclusion forsignature.

The modes of use of such an envelop are various. 5 and 6, it becomes anunsealed letter to a person whose address may be placed on the space onthe side, 1, which will be covered by the flap, 5, when it is folded outand gummed down as described, said flap then covering also the stampapplied in the upper right-hand corner marked Stamp. This envelop isparticularly intended, among other things, to be used for sending out toparties from whom responses are desired by By tucking in both of theflaps,

the original sender, for the sake of which he upon the return of theenvelop to him, and for which purpose instructionswith regard to suchreturn without postage are desirably printed upon the 'outer surface ofthe flap,"

' tion which the original sender desired to receive from the person towhom the envelop was sent out. The envelop is also particularly designedto be preserved in connection with the communication which may becontained upon its flap, so that when filed it shall constitute acomplete record, not onlyT of the correspondence which passed betweenthe parties, but also of the place and dates of mailing and receiving asindicated by the post-marks which the envelop will receive in passingthrough mail. For this purpose the end flaps, 3. and 4, are perforatedas described atthe folding line and the folding line at the iap, 6, isperforated, the intention lbeingthat when theenvelop is received, it

shall be opened by rupture at all ythree of said perforated lines, sothat lying flat the communication on the flap, 6, will be exposed andmay be read upon both sides by turning up the free edge ofthe flap toread the side which will be facing 'down or toward the body member, 1,of the envelop. I do not limit myself, however, to the particular mannerof `use of the envelop, but claim its construction as described,adapting it for-use in any ofthe Ways above indicated. To facilitateopening as described, the gum securing the narrow iaps, 3 and 4, stops alittle short of the folding line, 6, so that' a cutter can be introducedeasily to sever the flap, 6,at that line.

of said envelop side to permit sealing the Hap over said face of theenvelop.

2. An envelop open at one edge and having one side extended from saidedge to form a'foldable Hap dimensioned for tucking into the envelopthrough l'said open edge, adhesive being applied on one of the twosurfaces which face each other along the margin of lthe opening whensaid flap is so disposed within the envelop, said adhesive covering onlyan area closely adjacent said margin to 1avoid sealing down the entirearea of the 3. An envelop open at one edge and having both sidesextended from said edge to form foldable flaps, one of said flaps beingdimensioned to approximately cover one side of the envelop and havingadhesive applied to that surface which is continuous with the outer faceofthe envelop side 'from which the Hap extends to permit sealing saidflap over such outer face ofthe envelop, the vother flap beingdimensioned for tucking into the envelop through said open edge, andadhesive being applied on one of the two surfaces 4which face each otheralong the margin of theopening when said last-mentioned flap .is tuckedinto thev envelop, said adhesive covering only an area closely adjacentsaid margin to avoid sealing down the entire area of said Hap.

4l. An envelop having at two opposite edges folded flaps gummed onto oneside of the body for closing the envelop at said two ledges, the envelopbeing open at one edge and having one side extended from said open edgeto form a flap foldable at the line of said edge and dimensioned fortucking into the envelop throughsaid open edge, an adhesive area beingprovided at one of the surfaces which face each other along the marginof the opening when said flap is so tucked in,`the adhesive coveringonly an area closely adjacent said margin to avoid sealing down theentire area of the flap, and all three flaps being perforated at theirvfolded lines to permit opening the envelop at three edges, andunfolding it to flat form togive access to the unsealed area of the flapwhich ,y

was tucked in as described.

In testimony whereof I have hereunto set my hand at Chicago, Illinois,this 12th day of July, 1915.
